QSFP-DD Cages & Connectors
1X2 QSFP-DD Cage

1X2 QSFP-DD Cage

Shop LINK-PP 1×2 QSFP-DD cages — two-port single-row host receptacles with EMI spring fingers, optional heat sinks, and light-pipe variants for QSFP-DD panel rows. This leaf covers press-fit and solder assemblies for single-height panel cutouts on NIC and switch faceplates. These MSA host cages accept QSFP-DD pluggable modules in the QSFP-DD double-density envelope—not QSFP / QSFP+ / QSFP28 / OSFP cage hubs, and not pluggable module SKUs. Compare sibling 1X1 QSFP-DD Cage or 2X1 QSFP-DD Cage, return to the parent QSFP-DD Cages & Connectors hub, or browse Fiber Optic Cages & Connectors. Match termination, EMI style, and light-pipe options on each product page before ordering.

Frequently asked questions

01.What is a 1×2 QSFP-DD cage on this page?
This leaf lists LINK-PP 1×2 QSFP-DD host cages and cage/connector assemblies—metal receptacles that accept QSFP-DD pluggable modules at the faceplate. Compare sibling 1X1 QSFP-DD Cage or return to the parent QSFP-DD Cages & Connectors hub.
02.How does a 1×2 QSFP-DD cage differ from stacked 2×N cages?
A 1×2 cage places QSFP-DD port(s) in a single-height row. Stacked 2×N cages (for example 2X1 QSFP-DD Cage or 1X1 QSFP-DD Cage) double vertical density in the same panel width. Choose based on faceplate height and port count.
03.How does a QSFP-DD cage differ from QSFP, QSFP+, or QSFP28 cages?
QSFP-DD host cages use the QSFP-DD MSA double-density faceplate envelope sized for QSFP-DD modules. Classic QSFP, QSFP+, and QSFP28 family hubs cover the single-density QSFP envelope with different panel cutouts. Use this QSFP-DD leaf (and the parent QSFP-DD Cages & Connectors hub) for QSFP-DD host hardware; see QSFP Cages & Connectors, QSFP+ Cage & Connectors, or QSFP28 Cages & Connectors when you need those family hubs—not transceiver rate Shop pages.
04.Is a QSFP-DD cage the same as a QSFP-DD transceiver?
No. A QSFP-DD cage is the metal host receptacle (often with connector) soldered or press-fit onto the PCB; the pluggable transceiver or DAC/AOC inserts into that cage. This category sells cages and connectors for board design—not the pluggable modules themselves.
05.Press-fit vs solder, EMI spring fingers, heat sink, and light pipes—what should I check?
Press-fit pins speed board assembly without reflow on the cage; solder tails suit standard SMT/TH processes. EMI spring fingers improve chassis grounding at the faceplate; heat sinks help thermal paths on high-power QSFP-DD hosts; light pipes route link/activity LEDs to the bezel. For other port maps open 1X1 QSFP-DD Cage or 2X1 QSFP-DD Cage, or return to Fiber Optic Cages & Connectors.
